A comparative study of MAP2 immunostaining in areas 9 and 17 in schizophrenia and Huntington chorea.

Increasing evidence suggests that there may be significant morphological changes in the neuropil of the dorsolateral prefrontal cortex in schizophrenia. A controversial issue surrounding these deficits in the cortical neuropil is the confounding effects of antipsychotic (neuroleptic) medication as well as the question of generality to psychiatric disorders. To begin to address these issues we examined brains from Huntington's patients matched to a cohort of schizophrenics and controls.
